Depending on order placed your batteries may be shipped separately from your other items.

These batteries weigh in at only 4.98 grams and have all the punch of the 210mah batteries with 1 less gram of weight and this can make a huge difference in a micro drone. We have had great results with this battery and can get over 4 minute flight times using a standard 14000kv motor on an fpv setup inductrix with cruising it around. With our Chaoli insane motors we were still able to get close to 3 minutes of flight time and without that extra gram you can really feel the difference in the thrust. This is tested with cruising around at a decent speed as well but not pushing the limits or doing flips.
